Abstract:

A wireless mobile ad hoc network (MANET) is a collection of solely independent nodes that communicate with each other by forming a single hop/multi-hop network, and maintain connectivity in a decentralized manner. The important characteristic of the ad hoc network is that the nodes move randomly around the area of deployment making the topology highly dynamic. Because of this configuration and absence of infrastructure, an ad hoc network has been in increasing demand during emergency situations like human-induced disasters, military conflicts, emergency grounds, commercial applications and so on. The reliability of the ad hoc network is the most challenging and interesting issue because of its changing topology. This paper addresses and illustrates the effect of few scenario metrics, viz., network size, transmission range, and network coverage area, on the reliability measures (i.e., 2TRm and ATRm) by modeling MANET as Geometric Random Graph.
